Abstract

This thesis investigates the interaction between the rigid multi-body systems and fluid induced forces through a Fluid-Structure Interaction (FSI) approach. The study focuses on the motion of rigid bodies induced by fluid forces, employing a User Defined Function (UDF) coupled with ANSYS Fluent to model the dynamic interaction. The UDF allows the incorporation of complex motion equations, ensuring that the fluid-induced forces govern the movement of bodies within the fluid domain. The work includes the development and validation of the UDF with Six Degrees of Freedom (6DOF) method, followed by analysing the systems behavior by including damping effect, electromagnetic effect during power generation and multibody system dynamic analysis, where the motion of one body depends on another. Which are not possible by solely using the 6DOF approach in ANSYS Fluent solver. The results provide insights into the effectiveness of the UDF-based approach in handling complex fluid-structure interactions, with potential applications in fields such as aerospace, marine engineering, and biomechanics. The study also highlights the computational challenges and possible improvements for future work in RMB-FSI simulations.
